Low voltage d.c. surge protective device for traction systems. Selection and application rules for surge arresters. | Status: Current, Under review

1 Scope This Technical Specification applies to non linear metal-oxide resistor type surge arresters (MO surge arresters) without spark gaps designed to limit voltage surges on d.c. traction systems with nominal voltage up to 1 500 V. This Technical Specification applies to protection of equipment. Same principles for selection and application apply for MO surge arresters on d.c. traction systems with nominal voltage 3 000 V.
